The data on canoeable stage levels are from Canoeing Guide to Western Pennsylvania and Northern West Virginia, Eighth Edition, 1991, Pittsburgh Council American Youth Hostel (Page numbers indicated in first column) (Also available from Amazon.com). The current stage data are retrieved from the USGS Water Data for the Nation site, courtesy of the U.S. Geological Survey.

The low column represents the lowest possible stage reading at which the canoe trip is runnable. The high column, if available, represents the highest possible stage reading at which the canoe trip is runnable. These data are from Canoeing Guide to Western Pennsylvania and Northern West Virginia, Eighth Edition, 1991, Pittsburgh Council American Youth Hostel. Some of the low and high data are more reliable than others. The book mentions when the data are tentative. You should check the book before relying on the data in the above table. The Canoeing Guide has valuable information about each canoe trip. I highly recommend that you use the book along with this table. I've listed page numbers from the text for your convenience.
You should consider the flow rate as well as the stage when you determine if a stream is runnable. Appendix F in Canoeing Guide to Western Pennsylvania and Northern West Virginia gives detailed information about using gage data.
The Army Corps of Engineers maintains an excellent page about the Youghiogheny River's condition at the Yough Weekend Recreational Outlook page.
Each gage in the gage column links to the USGS page for that gage. This page gives flow rates, graphs of gage data over the past week, and other useful information.
If you are interested in only a few particular river trips, you can retrieve just those trips' data using their page numbers. For example, to get the data for the Casselman River trips, pages 331 through 339, go to http://www.learningdesign.com/cgi-local/rivergage?page=331,332,334,335,338,339.

P.S. I don't have much experience in canoeing these rivers, so I'm the wrong person to ask about their navigability. Check the Canoeing Guide of Western Pennsylvania and Northern West Virginia.
